“…In addition, the aromatic C@C stretching band around 1600 cm À1 may include contributions from water (OAH stretching), which is found to persist in even well dried coal samples, as observed in previous studies of coal [39,40]. Nevertheless, the results of FTIR analysis provide supportive information to that obtained by the NMR analysis.…”

“…In a study based on a set of Japanese coals, Fujii et al (1970) reported a similar variation, with the ratio of aromatic to aliphatic groups increasing slightly with carbon content until the carbon content reached approximately 88%, after which the ratio of aromatic to aliphatic groups increased dramatically with carbon content. This finding is also consistent with the results of other studies (Painter et al, 1985;Pradier et al, 1992;Mastalerz and Bustin, Fig.…”

“…The integrated areas in these two regions have been used to calculate the peak intensity ratio (H ar /H ali ) of the aromatic to aliphatic functional groups for the individual vitrinites in the coal samples, following a similar procedure to that used by Fujii et al (1970). Fig.…”

Attenuated total reflectance micro-Fourier transform infrared (ATR-FTIR) spectrometry has been successfully used to characterise coal macerals, in particular telocollinite, and to investigate changes in the aromatic and aliphatic functional groups in the telocollinite, over a wide rank range (Rv max from 0.39 to 3.52%) in coals from the Bowen Basin, Queensland, Australia. The results show that ATR-FTIR is very sensitive to the increasing aromaticity (the fraction of carbon atoms involved in aromatic units) of the telocollinites, and thus is a very useful tool to study the evolution of aromatic and aliphatic functional groups with maturation of telocollinite, and also to differentiate and characterise the various macerals in coal samples. In comparison with other micro-FTIR techniques, ATR-FTIR has many advantages: (1) no difficult and time-consuming procedures are required to obtain "pure" maceral separations, or for preparation of thin coal slices; (2) the ATR-FTIR spectra have better signal-to-noise ratio and increased sensitivity; (3) the ATR-FTIR spectra are similar to absorption spectra, but without significant spectral distortion.

“…The band at 3,400 cm-1 (H-bonded OH) is broad due to extensive hydrogen bonding (7). In lignite, the bands at 2,920 and 2,850 cm-1 (aliphatic C-H stretching) do not appear to indicate a high degree of aliphatic hydrocarbon structure (4,8). This is typical of lignite coal.…”

We report that two species of basidiomycete fungi ( Polyporus versicolor and Poria monticola ) grow in minimal liquid or solid medium when supplemented with crushed lignite coal. The fungi also grow directly on crushed lignite coal. The growth of both fungi was observed qualitatively as the production and extension of hyphae. No fungal growth occurred in minimal agar medium without coal. The fungi degraded solid lignite coal to a black liquid product which never appeared in cultures unless fungi and coal were present together. Apparently, lignite coal can serve as the principal substrate for the growth of the fungi. Infrared analyses of the liquid products of lignite degradation showed both similarities to and differences from the original lignite.
